SIWOM1 series MCCB

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 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 are shown in the figure

Installation class: Ill

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;

2The 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;

4After 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. When the circuit is short-circuited or severely over loaded, the armature of overcurrent tripper is closed so that the free tripping mechanism acts and the main contact disconnect the main circuit. When the circuit is over loaded, the thermal element of the thermal tripper is heated so that the bimetallic strip is bent to push the free tripping mechanism to act. When the circuit is under voltage, the armature of under voltage tripper is released to make the free tripping mechanism act. The shunt tripper is used for remote control, whose coil is powered-off during the normal operation; when remote control is required, press the shunt button to make the coil powered-on so that the armature drives the free tripping mechanism to act to make the main contact disconnected:

5The dynamic contact, static contact and contact lever of the circuit-breakers are designed to be parallel , the electric repulsion generated by short circuit disconnects the dynamic and static contacts, and breaking capability and current limiting capability are high;

6The arc extinguish chamber of circuit-breakers has a metal grid-plate structure , the contact system is provided with a repulsion current limiting mechanism, and therefore, the circuit-breaker has high breaking capability and current limiting capability;

7The circuit-breakers are provided with a compound tripper. Inverse time limit action is that the bimetallic strip is bent by heating to drive the tripper to act, and instantaneous action is that the iron core armature mechanism drives the tripper to act Tripping modes include thermal , electromagnetic and compound tripping

Scope of application of SIWOM 1 circuit-breakers

SIWOM1 moulded case circuit-breakers, whose rated insulation voltage is 800V (500V for SIWOM 1-63). They are applicable to infrequent operation and infrequent motor startup in the circuits with AC frequency of 50/60Hz, rated operational voltage of 690V and below, and rated operational current of up to 800A (lnm630A and below). The circuit-breakers provide overload, short circuit and under voltage protection, which can protect the circuit and power supply device from damage;

In accordance with the rated ultimate short-circuit breaking capacity, the circuit-breakers can be divided into three types of L (Standard type),

M (Moderate breaking type) and H (High breaking type); The circuit-breakers are featured by small volume, strong breaking capability, short flash over, anti-vibration, etc,

The rated ultimate short-circuit breaking capability 35-50kA is mainly applicable to civil residential buildings, shopping malls, hospitals, schools, public buildings, and industrial plants; The ultimate limit short-circuit breaking capability 70-100kA is mainly applicable to power supply-level power equipment.
