Описание в каталоге: CM-PVS.81S Three-phase monitoring relay 2c/o, 0,0,1-30s, L1-L2-L3=3x200-400VAC
Длинное описание: The CM-PVS.81S relay is from the CM three-phase monitors range. This relay operates with a rated control supply voltage / three-phase measuring voltage of 200-400 V AC and has a 2 c/o output with contacts rated at 250 V / 4 A. The CM-PVS.81S monitors the phase parameters over/undervoltage and phase failure. The corresponding threshold values are adjustable. Phase sequence monitoring as well as an ON or OFF tripping delay are selectable. The tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals.
Описание в каталоге: CM-LWN Motor load monitor, 2x1c/o L1-L2-L3=500VAC, L1/k-L1/l=5A,380-440VAC
Длинное описание: The CM-LWN relay is from the CM motor load monitors range. This relay operates with a rated control supply voltage of 380-440 V AC, has a 2 x 1 c/o (SPDT) output with contacts rated at 250 V / 4 A and works according to the closed-circuit principle. Its measuring principle is based on the evaluation of the phase shift between the voltage and the current in one phase of single- or three-phase asynchronous motors (squirrel cage). The measuring circuit is designed for measuring voltages of 110-500 V AC and measuring currents of 0.5-5 A AC. The window (over- and underload) monitoring allows setting of two individual threshold values, one for maximum load and one for minimim load. The hysteresis is fixed at 4 ° related to the phase angle. The tripping delay is adjustable within a range of 0.2 to 2 s and the start-up delay within a range of 0.3 to 30 s. A sealable transparent cover for protection against unauthorized changes is available as accessory.
