Siwom1L Series Elcb

SIWOM1L Series ELCB: Product description : SIWOM1 L moulded case circuit-breakers with residual current protection (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 SIWOM1L circuit-breakers 1 SIWOM1L moulded case circuit-breakers with residual current protection (hereinafter referred to as leakage circuit-breakers) provide ground fault protection. The power supply sampling for leakage protection module of conventional residual current protective circuit-breakers is two-phase and those for this series of leakage circuit-breakers is three-phase. In case of loss of any phase, the leakage protection module of circuit-breakers still works normally, 2 Adjustable at the site: The rated residual action current lrn and residual current action time (non-delay and delay) is adjustable according to the actual situation at the site; 3 Low-voltage protection: When the phase voltage is reduced to 50V, the leakage protection module still works normally; 4 Leakage alarm output function: When the residual current of a device or line reaches or exceeds the set point, the circuit-breakers with leakage alarm unit module outputs a passive contact signal to drive the corresponding alarm device, The circuit-breaker is featured by small volume, strong breaking capability, short flashover,anti-vibration. etc Product origin : Shenyang Key Specifications/Special Features :SIWOM1L-16A~630A/4300
