RELAY CONTACTOR SIEMENS 3RH11222BA40

RELAY CONTACTOR SIEMENS 3RH11222BA40

Control relay 3RH range of SIEMENS Sirius 2 NA + 2 NC

Climate-proof contactor relay with accidental contact protection. RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) can be plugged into all contactor relays to dampen aperture transients in the coil.

Size S00
High degree if there is contact stability with current and low voltages
Suitable for use with solid-state circuits with currents ≥ 1 mA and a voltage of ≥ 17 V
Expandable by up to four contacts for use with pressurized auxiliary switch blocks

The NA contact shutdown delay and NC contact ignition delay increases if the contactor coils are attenuated against voltage peaks (noise suppression diode 6 to 10 times; diode mounts 2 to 6 times, varistor +2 to 5 l ms).

SIEMENS controller for feeders up to 5.5 kW. The complementary nature of the devices allows quick and easy assembly, for example, of starter motors and inverters. A perfect match between contactors, overloads, circuit breakers and accessories for the same power values that provides a uniform panel appearance and standard widths without reduction of side mounting to save space.
