DM30(DM32・DM33) DM50(DM52 DM53)
Since it is a completely electromagnetic circuit breaker, it has operating characteristics that are not affected by surrounding temperature! Immediate re-energization after tripping is possible! Fine ratings can be selected from low currents!
1. Applications suitable for DM30 (30AF) Small capacity power branching in control panels and operation panels Small current branching circuits for instrumentation equipment, PLC power supplies, DC power units, indicator lamp circuits, etc. Protection just before low ampere devices Even in circuits around 1A to 10A, which are less commonly provided by general MCCBs, it can be installed as a panel breaker with a sense similar to that of a circuit protector. Space-saving branching within panels Due to its compact shape, it is suitable for cases where space-saving is desired in panels with many branching circuits. 2. Applications suitable for DM50 (50AF) Power panels and power branching circuits Branching circuits for small three-phase induction motors (pumps, fans, compressors, etc.) and heater loads at 200V class. Main receiving section of distribution boards and medium capacity main line branching The main breaker of a small panel when DM30 is used as a branching circuit, or medium capacity feeder circuits of power distribution boards. Systems with slightly larger inrush current and short-circuit capacity Busbar direct connection circuits where the power capacity is large, and there is a risk that the rated interrupting capacity (kA) may be insufficient with 30AF.
