5SV4644-0
SENTRON 5SV4644-0 is a four-pole RCCB, Type AC, rated current 40A, operating current 300mA, rated voltage 400V AC, without overload protection, and is commonly used for leakage and fire protection of main or branch circuits in distribution boxes.
Product Positioning
The SENTRON 5SV4644-0 is a Siemens SENTRON series four-pole pure residual current circuit breaker (RCCB) that provides circuit leakage fire protection with an operating current of 300mA.
Core Product Advantages and Features
Four-pole pure leakage protection
The 4-pole design can simultaneously monitor the leakage current of the three phases and the neutral line, but does not include overload or short-circuit protection.
Rated current 40A
Suitable for medium-load circuits, such as air conditioning and power equipment circuits.
300mA operating current
It is classified as a fire protection level sensitivity, reducing the probability of unnecessary tripping.
400V AC rated voltage
It meets the application requirements of three-phase 400V power distribution systems.
