Siwom1 Series Mccb

SIWOM1 Series MCCB: Product description : Product General SIWOM1 moulded case circuit-breakers (hereinafter referred to as circuit-breakers) use thermomagnetic tripper and they are developed and manufactured by the Company with the latest circuit-breaker technology. The circuit-breakers are featured by good-looking appearance, compact structure, long service Iife, low rated power consumption, stable performance, easy installation and superior performance, and they provide users with safe and reliable Protection. The circuit breaks has disconnecting function Indication of 0 and OFF positions is provided, and when the contact is open, the handle points at 0 and OFF positions; The position of rotary handle or operating mechanism is consistent with the noumenon , which does not affect reliability of the circuit-breakers Reverse incoming line is not allowed for the circuit-breakers, and only Pole 1, 3 and 5 are allowed to connect with the power supply line and Pole 2, 4 and 6 with the load line The circuit-breakers may be installed vertically (i.e., vertical installation) or horizontally (i.e., horizontal installation). Current limiting capability is provided; the whole series are designed to have a current limiting acting mechanism that extinguishes the electric arc before the expected short-circuit current reaches its peak to suppress the impact of short-circuit current on the circuit. The actual and expected breaking short-circuit current peaks of current limiting acting mechanism. Main features of SIWOM 1 circuit-breakers 1 The circuit-breakers have merits of multiple protection functions (overload, short circuit, under voltage protection, etc.), adjustable action value, strong breaking capability, easy operation, safety, etc., therefore they are widely used now; 2 The circuit-breakers may be used to connect and disconnect load circuit or control motors that do not start frequently. Their functions are similar to total functions of some or all of the electric equipment such as knife switch, overcurrent relay, under voltage relay, thermal relay, leakage protector, etc., and they are important protective devices in the low-voltage power distribution network: 3 The circuit-breakers are internally more sophisticated, but relatively simple in principle. They connect with inductor between the incoming and outgoing lines. When the current exceeds the rated value, the coil drives the iron core to provide protection; 4 After the main contact of the circuit-breakers is manually or electrically closed, the free tripping mechanism locks the main contact at the closing position. Coil of overcurrent tripper and thermal element of thermal tripper are connected with the main circuit in series and coil of under voltage tripper is connected with the power supply in parallel.
