Series 5TEB81/3/4/5 Contactors On / Off Switch for DIN rail assembly Types with 32A to 63A applicable as load disconnecting switches after EN 60947-1 With separate handle locking device Sealable witch position Auxiliary current switch can be mounted Position indicator red / green on 5TE83, 4, & 5 units Auxilary switches available for all 5TE8 switches Mechanical life span: 5TE81: 25,000 position changes and 5TE83/84/85: 20,000 position changes Electrical life span: 5TE81/83/84: 10,000 position changes and 5TE85: 5,000 position changes Kind of connection: C-clamps Dimensions (HxD): 90x70mm Ambient temperature: -5°C→+40°C Standards EN 60947-1 Standards EN 60947-1 Siemens RCDs, RCBOs, RCCBs and MCBs Type B characteristic offers instantaneous short circuit response level of 3-5 x normal rated current, making it suitable for circuits with moderate inrush currents such as filament lamps, heating loads and most domestic/small building protection applications.,Type C characteristic offers short circuit response of 5-10 x normal rated current, making it ideal for circuits with higher inrush currents such as motor control and fluorescent lighting installations in industrial buildings where nuisance tripping might occur if a faster type was used. Type D characteristic is designed for high inrush loads. Magnetic trip point - 10 to 20 times In rating. Thermal trip point - 1.13 to 1.45 protector rating. Type AC characteristic ensure tripping for sinusoidal, alternating currents, whether they be quickly applied or slowly to increase.
