1SYS273112R0504 ABB MCB SB203 M-C50 NA - 3 Pole+Neutral, 50A, C Curve

The ABB 1SYS273112R0504 is a 3-pole + neutral miniature circuit breaker rated at 50A with a C curve and 10kA breaking capacity. It protects the circuit against overload and short circuit.

Choose the ABB 1SYS273112R0504 for circuits that need 50A, C-curve protection where the fault level is within 10kA. Matching the curve to the load avoids nuisance tripping.

MCBs of this rating are used as distribution board incomers and on sub-main and high-current circuits.

A B curve MCB trips instantaneously at 3 to 5 times its rated current and suits resistive loads such as lighting and heaters. A C curve MCB trips at 5 to 10 times and is the general choice for mixed and small motor loads. A D curve MCB trips at 10 to 20 times and is used for loads with high inrush current such as small transformers and motors with heavy starting current (motors still need an overload relay or MPCB for overload protection).
