Since its introduction in 1994, the B&C SPECIALITY PRODUCTS BC320 Starter for Continental engines has established an impressive service record as the ONLY starter design on the market that has provided reliable, long-term service for these engines. 

Suitable for installation on Continental engines (C-75, C-85, C-90, C-145-2, O-200, IO-240, O-300-A, -B, and -C, and GO-300-A, -B, and -C) it solves all the problems that other starter designs have had:  worn-out clutches, broken pinions, nagging oil leaks, and catastrophic failure modes. Featuring the durability of all-steel gears and heavy-duty ball-bearings, and the efficiency of a high-torque series-wound motor, it provides greater starting torque, while saving 4.3 to 5.2 lbs. over the old key-type and pull-cable type starters (respectively).

The B&C SPECIALITY PRODUCTS BC320 Starter is STC-PMA approved for use in certificated aircraft, and is available with or without the STC (*). Two installation kits are also available:  one for replacing a key-type starter (Installation Kit 501-1), the other for replacing a pull-cable type starter (Installation Kit 501-3). For key-type starters, before installing the BC320, you will need to remove the needle bearing pressed into the engine case & install the supplied plug in its place. For pull-cable starters, before installing the BC320, you will need to cut off the 9/16 steel shaft that is installed in your engine case.

Other versions of BC320 Starter for 12v and 24v electrical systems (BC320-2, 12v Counter-Rotating or the 24v BC320-3) are also available.

(*) For the issue of the STC, the aircraft make and model, aircraft registration and serial number are required.

The KLIXON® 7270/7271 series circuit breakers were designed to utilize less behind panel space while protecting wire and cable in aircraft and ground support equipment on either 120 VAC, 400 Hz or 30 VDC systems.

These circuit breakers are available with neck mounting (7270-1 and 7271-8) or standard cover plate (7270-7 and 7271-3). In each of these KLIXON® circuit breakers, the bi-metallic element assures uniform current distribution throughout its responsive area. This design reduces current density at the critical areas, resulting in an element having a much higher interrupting capability than conventional design. Inherently resistant to shock and vibration, the KLIXON® disc element is capable of precise calibration settings and will retain the initial calibration within close tolerances throughout the service life of the breaker. Both circuit breakers have conventional actuator action; i.e., the toggle actuator on the 7270 moves to the OFF position for trip indication and the button the 7271 pops out. A standard black button with a white collar is used. For additional information please refer to the attached documentation.

The Series 16 from MECHANICAL PRODUCTS (MP) is a proven reliable, single-pole thermal circuit breaker with a robust design. This series is suitable for diverse applications such as medical equipment, uninterruptible power systems (UPS), portable generators, welders, industrial cleaning equipment, and transportation. These heavy duty circuit breakers are ideal for use with aircraft alternators and other applications using high amperage.
