63A MCB Circuit Breake Residual Current Operated Circuit Breaker
Application
DZ30LE-32 residual current circuit breaker (hereinafter call RCB)
is mainly operating in the line of AC 50/60HZ, rated voltage 230V,
rated current up to 32A, used to protect from electric shock,
electric leakage of equipment, also prevent overloading, short
circuit, also to switch on/off electric devices or light system
non-frequently, especially suitable for industrial and commercial
lighting system. If necessary, over-voltage protection can be
added, o/v value Uvo=280V. The product complies with GB 16917.1,IEC
61009-1 standards.

Structural features
Small size, compact structure. the price is cheaper than other same
productThe shell and some functional parts made of high flameproof,
hi-temperature withstand, impact withstand plastic material.The product directly connected with neutral line, to avoid wrong
connection and leading to electric shock.The product adopted the latest circuit design and hi-performance
components, it can withstand high surging current and over-voltage
and avoid wrong tripping.Rail mounting, easy installation and save time.
