Neutral bus bars with SCHNI-type insulator are intended for electric and mechanical connection of neutral operating and protective conductors. Constructively, SCHNI buses are made of a latten alloy bus placed onto a plastic insulator made of self-extinguishing plastic.
Standard exploitation conditions:
- ambient temperature: from –40 to +50 C;
- relative humidity: under 90%.

Protection of heat release mechanism by plexiglass against change of factory settings.

Silver-containing composite weld deposition increases the wear resistance of the contact group and reduces the contact resistance.

Unified casing with the ability to connect additional devices does not require dismantling, as well as provided with the ability to self-connect.

The status indicator of the main circuit provides accurate information on the status of contacts regardless of handle position.

The improved switch handle of wider size with increased contact area facilitates the switching process.

Increased size of the screw head with multiple-purpose slot (+, -) facilitates the assembly and prevents the falling out of screws during installation.

The switch design provides for two types of protection against overload and short circuit, that significantly improves the protection of distribution and group circuits.

Notches on the contact clamps reduce heat loss and increase the mechanical stability of the connection.

Special casing design with increased heat transfer allows you to raise the loading capacity by 10%.

Bus connection to the automatic circuit breaker allows to reduce the contact resistance and provides a 2- or 3-wire connection of the line for uniform distribution of bus load.

Circuit breaker BA47-29M 3P 8A 4.5kA C IEK

The detectors are designed to switch on and off the load automatically within specified time interval depending on presence of moving objects in the detector sensing area and illumination level.

Protection of the mechanism of the thermal release with a plexiglass insert from changing the factory settings.

notes on contact clamps reduce heat losses and increase the mechanical stability of the connection.

the ability to simultaneously join the FORK tire and a flexible conductor to distribute the power supply through the upper clamps, as well as the possibility of connecting the PIN bus.

The attack from the silver -containing composite increases the wear resistance of the contact group and reduces the transition resistance.

an advanced ardent system: increased service life, increased resistance to short -circuit currents: patent No. RU 139886.

Additional protection against the burning of the circuit of the circuit breaker and heat removal due to plastic and metal anti -carbon plates.

quick installation and additional reliability of mounting on a DIN-rack using a latch with a double fixed position.

The presence of the contact position indicator.

the increased strength of the case in the attachment zone of conductors due to two additional rivets and a monolithic front panel.
