Larson Electronics HLSW-PB20-3PSW Non-Metallic Explosion Proof Maintained Contact Switch – 3-Position Selector Switch – C1D2 – C2D2 –

Description:

The HLSW-PB20-3PSW from Larson Electronics is a non-metallic maintained contact switch that is rated for Class I Division 2 Groups A, B, C & D, Class II, Division 2, Groups E, F & G and Class III, Divisions 1 & 2 hazardous environments. This ATEX certified 3-position selector switch switch has a din rail mount design and is constructed of an impact resistant glass reinforced non-metallic material with silicone gaskets. The HLSW-PB20-3PSW has a black housing color with a black two-way switch and boasts a compact size for convenient mounting and use.

This Class I Division 2 Groups A, B, C & D rated non-metallic maintained contact switch is designed for din rail mounting. It is ideal for mounting and use in petroleum refineries, chemical plants, petrochemcial plants and other facilities where similar conditions exist. The HLSW-PB20-3PSW has explosion protected contact blocks that are rated for voltages up to 690V AC, is capable of handling 20 amps for switching duty and has a horsepower rating of 2 HP. This 3-position selector switch also features silver alloy contacts with gold flashing. This non-metallic maintained contact switch has an ambient operating temperature of -50?C to +60?C and can be used in conjunction with motor starters or contactors for remote operation of motors.

The HLSW-PB20-3PSW C1D2 non-metallic 3-position selector maintained contact switch features a non-metallic housing that is constructed of a PA6 glass reinforced antistatic material that is impact resistant, f1 UV resistant and has a flame retardant rating of V-0. The housing on this switch is black and the switch itself is also black which offers plenty of contrast against the silver legend plate that is marked Hand-Off-Auto for easy visibility of the switch and its current position. This switch has a 1/2″ NPT hub and features silicone gasketing throughout. The HLSW-PB20-3PSW has two normally open contact blocks. Normally open is a contact that does not flow current in its normal state. In the case of this switch, the normally open contact would be labeled as “OFF” because the circuit is “open” or not allowing current to flow.
