TE Connectivity W23 Thermal Circuit Breakers

Pilots HQ carries selected TE Connectivity W23-series circuit breakers in several amperage ratings. These push-pull thermal breakers are designed to interrupt current when an overload condition causes the internal thermal element to trip.

W23 breakers feature a visible trip indicator, screw-terminal connections, and trip-free operation. Trip-free construction prevents the breaker from being held closed against a continuing overload. Depending on the specific rating and application, a W23 breaker may also function as a manual on-and-off control.

Selecting the Correct Circuit Breaker

Circuit breakers must be selected according to the electrical load, conductor size, system voltage, installation requirements, environmental conditions, and approved technical data. Matching the mounting style or amperage marking alone does not establish aircraft eligibility.

• Confirm the complete TE Connectivity part number.
• Verify the required current rating and electrical characteristics.
• Check the terminal configuration and mounting dimensions.
• Review the aircraft wiring diagram and maintenance manual.
• Confirm any applicable OEM or alternate part number.
• Verify that the breaker’s approvals are appropriate for the installation.

TE identifies W23-series products as UL 1077 supplementary protectors. This classification should be considered during component selection and does not replace aircraft manufacturer approval, engineering authorization, or other applicable airworthiness requirements.

PIDG Ring Terminals for Electrical Wiring

The TE Connectivity assortment at Pilots HQ includes multiple PIDG insulated ring-tongue terminals. These closed-barrel crimp terminals are manufactured in several wire ranges, stud sizes, insulation colors, and configurations for secure attachment to compatible threaded electrical connections.

Selected terminals use tin-plated copper conductors with nylon insulation and integral insulation support. Available listings include terminals for common wire ranges such as 22–16 AWG and 16–14 AWG, with different ring openings for the required stud or screw size.

Advantages of Properly Crimped Ring Terminals

• Ring-shaped tongues remain captured beneath installed hardware.
• Closed barrels support consistent conductor placement during crimping.
• Insulation support helps reduce stress where the wire enters the terminal.
• Color coding assists with identifying nominal wire-size ranges.
• Tin-plated copper components provide dependable electrical conductivity.

A terminal’s color should not be the sole basis for selection. Always verify the TE part number, conductor size, insulation diameter, stud opening, material, temperature rating, and applicable qualification before installation.

Butt Splices, Environmental Splices and Wire Caps

TE Connectivity butt splices provide an in-line method of joining compatible conductors. Pilotshq listings include insulated PIDG butt splices as well as selected heat-shrinkable environmental splices designed to seal the completed connection against moisture and contaminants when installed according to the manufacturer’s process.

Environmental splice selection requires attention to conductor gauge, insulation diameter, sealing material, heating procedure, and installation tooling. The correct controlled-heat equipment should be used to recover heat-shrinkable components without overheating adjacent insulation or damaging the conductor.

The collection also includes pre-insulated wire caps for terminating compatible stripped conductors. Wire caps should only be used where permitted by the applicable wiring instructions and must be correctly sized and crimped with approved tooling.

Knife-Disconnect Terminals and Serviceable Connections

Knife-disconnect terminals create a separable electrical connection that may be useful where wiring must be disconnected for servicing or equipment removal. The terminal and mating component must be compatible in size, material, wire range, and electrical rating.

Separable terminals should be positioned and supported so vibration, conductor tension, or nearby structure does not place excessive mechanical load on the connection.

TE Raychem Cable and Heat-Shrink Accessories

Pilots HQ carries selected TE cable-accessory products, including silicone tape and TE Raychem adhesive materials. These products may be used for compatible wire-harness protection, insulation, sealing, strain relief, or heat-shrink system installation when specified by the applicable technical procedure.

The TE Raychem S1125 two-part epoxy system is designed for compatible bonding and sealing applications, including use with specified heat-shrink tubing systems. Mixing ratios, preparation, working time, curing conditions, shelf life, and material compatibility must be verified before use.

Aircraft Wiring Installation Practices

Reliable aircraft electrical work depends on more than selecting a terminal or breaker with similar dimensions. Wiring components should be installed using approved crimp tools, dies, positioners, heat sources, torque values, and inspection procedures.

• Inspect conductors for corrosion, broken strands, heat damage, and contamination.
• Strip insulation without nicking or cutting conductor strands.
• Use the crimp tool and die specified for the terminal family.
• Confirm conductor insertion and insulation support before crimping.
• Inspect completed crimps according to approved acceptance criteria.
• Support wiring to prevent chafing, vibration damage, and excessive strain.
• Protect splices and terminals from fluids, heat, abrasion, and sharp structure.

Verify TE Connectivity Part Numbers Before Ordering

TE Connectivity produces an extensive range of components for aerospace, industrial, automotive, communications, and other applications. A TE brand name or similar appearance does not establish that a component is suitable for a particular aircraft.

Before ordering, compare the exact part number with the aircraft illustrated parts catalog, wiring diagram, maintenance manual, equipment installation manual, approved modification data, or other applicable technical documentation. Confirm wire gauge, voltage, amperage, temperature range, terminal size, environmental sealing, agency approvals, and installation requirements.
