breaker to trip. With mid-trip, handle moves to the mid position on electrical trip of the circuit breaker. With mid trip handle with alarm switch, handle moves to the mid position and the alarm switch actuates when the circuit breaker is electrically tripped. Physical Number of Poles 1-6 poles ≤ 50A; 1-4 poles @ 51-70A; 1-2 poles 71-100A. UL489
Standard tripping schemes and trip circuit supervision schemes ...
These schemes are the frequently used and are provided in most medium voltage switchgear applications. 1. General - Functional Requirements. A protection relay is usually required to trip a circuit breaker (CB). The power required by the trip coil of the CB may range from 50 W for a small distribution CB to 3000 W for a large EHV CB.
The Basics Of Circuit Breaker Tripping Units
The thermomagnetic trip unit consists of two parts: The thermal trip unit - Made up by a bimetal thermal device which actuates the opening of a circuit breaker with a delay depending on the overcurrent value. This trip unit is intended for the protection against overloads. The magnetic trip unit - Made up by an electromagnetic device, with ...

Short-time pickup is adjustable from 1.5 to 10 times the trip unit ampere setting (Ir). For example, a 1000 ampere frame can be adjusted to trip anywhere from 1500 to 10,000 amps. The switch also has an "OFF" position to eliminate short-time pickup and short-time delay. Short-time pickup used for selective tripping.

How does Trip Circuit Supervision Work?
Here fault in the circuit means any break or open circuit. In this post we will be discussing the working principle of trip circuit supervision. Basically, a breaker is equipped with two trip coils. Both the trip coil energizes if relay issues a tripping command. On energization of trip coil, breaker mechanism opens the circuit breaker.

Tripping Curves of Circuit Breaker. B, C, D, K & Z Trip Curve
A circuit breaker has two types of tripping unit i.e. thermal and magnetic tripping unit. Thermal Tripping Unit: the thermal tripping unit is used for protection against overloading. It uses a bi-metallic contact that bends with a change in temperature. The current flowing through the bimetallic strip heats up contact & trip the circuit breaker.
