The 2TC2-5 is a 5 A miniature push-pull circuit breaker for aerospace electrical power-distribution applications. It is identified by manufacturer part number MS3320-5.

Part of the TC-series circuit breaker range, this compact and lightweight device features a trip-free design: it cannot be held closed when an overload condition is present. The series is designed for high-performance electrical protection where installation space and weight are important considerations.

  • Product designation: 2TC2-5
  • Manufacturer part number: MS3320-5
  • Current rating: 5 A
  • Miniature push-pull circuit breaker format
  • Trip-free overload protection design
  • Suitable for aerospace electrical and avionics power-distribution installations, subject to the applicable technical documentation and installation requirements

Supplied as one each.

Overview

Single–phase TC devices are the smallest, lightest high performance aircraft circuit breakers available today. They represent the state-of-the-art protection of today’s aerospace power systems. Their light weight and small size make them especially well suited for aircraft, avionics and electronic systems.

Coordination
The 2TC series breaker ratings are coordinated so any rating will trip before another rating twice its capacity in the event of a fault. of up to 6,000 amps let–thru current. This results in improved overall equipment performance since only the smallest faulted circuit is interrupted, while larger circuits remain operational.

Ambient Temperature Compensation
Ambient compensated circuit breakers let designers specify smaller gauge wire where the circuit breaker and wiring are exposed to different ambient temperatures. They are especially suited for application where ambient temperature exceeds the 160°F (71°C) maximum of non–ambient compensated thermal circuit breakers. The TC series may be applied where operating temperatures are as high as 250°F (121°C) with no derating of the circuit breaker. This eliminates the need for cooling air and allows substantial weight, space, and cost savings.

Trip–Free
The complete line of TC series circuit breakers is trip–free. The circuit breaker cannot be maintained closed during an overload even with the actuator button held closed.

High Short Circuit Capacity
For its miniature size, the 2TC series offers unusually high current interrupting capacity. Overloads can be safely interrupted without affecting calibration or operating performance in the standard 2TC series for: • Overloads up to 6,000 amps at 28 VDC • Overloads of 2,000–3,500 amps at 120 VAC, 400 Hz
