Description
Schneider RM22TA33 Control Relay Three-Phase Asymmetry 8 Amps 380-480 Volt AC 2 x C/O
This Schneider Electric Zelio Control RM22TA asymmetry control relay allows monitoring of power supply circuits in 3-phase networks. It has 2 changeover contacts double pole double throw with a supply voltage of 380-480Vac. It is mountable on DIN rail. This modular 3-phase control relay is ideal for monitoring of electrical values in industrial and building control panels. It applies to a wide type of industrial automation applications such as hoisting packaging lifts textile water. It has one of market slim form-factors with 22.5mm width allowing for a flexible and easy installation on DIN rail using the same space as any modular 2-pole DIN device. It also offers a selectable memory function integral LED for indicating control status sealable cover with simple and precise settings with screw trimmers.
