ABB MS165-20B Motor overload relay 1 pc(s) Adjustment range (amperage): 14 - 20 A Switching voltage (max.): 400 V AC (W

MS165-B stands for the compact and powerful series in 55 mm width for the motor protection up to 30 kW (400 V) in rail applications. The devices comply with current rail standards and are therefore suitable for installation in passenger areas and driver's cabs of trains, which frequently operate in tunnels and underground.

The turning handle can be locked in 0 position using a padlock. Auxiliary, signal and short circuit contacts as well as undervoltage and working current releases can be installed without any tools, this accessory can also be used for MS132-B. 3-phase rails for 125 A allow the common feed of several motor protection switches. Accessories for switch cabinet installation and terminal covers complete the assortment. MS165-B have trip class 10, are temperature compensated and phase failure sensitive. They meet the international rail standards IEC 60077 in the applicable parts, IEC 61373 (category 1, class B) for shock and vibration as well as the European safety standard EN 45545-2 for fire and smoke.
