1SYS274012R0201 ABB MCB SB204 M-D20 - 4 Pole, 20A, D Curve

The ABB 1SYS274012R0201 is a 4-pole miniature circuit breaker rated at 20A with a D curve and 10kA breaking capacity. It protects the circuit against overload and short circuit.

Choose the ABB 1SYS274012R0201 for circuits that need 20A, D-curve protection where the fault level is within 10kA. Matching the curve to the load avoids nuisance tripping.

D-curve MCBs like the ABB 1SYS274012R0201 are used on circuits with high inrush current, such as small transformers and motors with heavy starting current, and welding equipment, rated up to 20A.

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).
