RS PRO MCB, 2P, 4A Curve C, 240V AC, 240V DC, 10 kA Breaking Capacity

RS PRO 240 V DIN Rail Mounted DHMZ Series of MCB’s (miniature circuit breakers) Type B (curve), Type C (curve)

For reliability, efficiency and up to date technology the RS PRO range of MCB’s (miniature circuit breakers) offer you a selection of MCBs designed to protect your electrical circuits from both overloads and short-circuits, meeting the needs of residential, commercial, and industrial applications.

With breaking capacities of up to 10 KA all in accordance with IS/IEC 60898-1 and IS/IEC60947-2 RS PRO MCB’s include many features including inspection windows, safety terminals, large cable terminals, Bi stable clip, positive contact indication, auxiliary contacts, and air circulation. All offered with IP20 protection within a thermoplastic flame-retardant moulded casing for clip on DIN rail mounting. With a choice of 1 to 4 Poles, rated currents of 0.5 to 63 A, independent thermal magnetic tripping system, type B and Type C MCB’s provide the short circuit electrical protection necessary for many applications.

Miniature Circuit Breakers, MCB, is the standard recognized term for MCB but also recognized as Circuit Breakers, Mini Circuit Breakers, Trip Switches, Circuit Protectors and Breakers.
