The Larson Electronics EPO-250V-3W4P-30A-ICB explosion proof power receptacle with built in circuit breaker is approved for Class I Division 1 & 2, Class II Division 1 & 2 and Class III and provides a safe and secure power connection for portable or stationary electrical devices and equipment in hazardous locations.
This explosion proof power receptacle with integrated circuit breaker is ideal for operators seeking a high quality explosion proof power outlet receptacle rated for use in hazardous areas designated Class I Div 1 & 2, Class II Div 1 & 2, and Class III. This three wire, four pole unit is constructed of copper free aluminum and contains an integral circuit breaker which provides short circuit and thermal overload protection as well as manually operable protection during connection and disconnection of electrical cables. This unit is easily wall mounted via two screw slot tabs at the side of the housing and provides two, 1 1/4" NPT tapped openings located on the top and the bottom of the housing for connection to approved electrical conduit.
A neoprene bushing receptacle seal prevents the entry of water when a cable is connected and a spring loaded receptacle door prevents the entry of dust when the unit is not in use. This unit is rated to handle electrical loads up to 30 amps and is suitable for use in environments where combustible dusts and particulates may be present.
The EPO-250V-3W4P-30A-ICB explosion proof power receptacle and housing unit is constructed of corrosion resistant, non sparking aluminum and finished with an epoxy powder coating. The internal receptacle plug contacts are deeply recessed to protect against accidental touching and are spring loaded and constructed of brass for superior connectivity. The plug receptacle uses mechanical cable clamps to prevent strain on connecting cables and meets or exceeds U.L. strain relief pull-out requirements. A neoprene bushing fitted inside the connector receptacle provides positive sealing against water ingress when power cables are connected. 1-1/2" NPT tapped conduit openings are provided on the top and bottom of the unit for easy and secure connection to main power line supplies.
Integral circuit protection: This unit contains an interlocked disconnect switch and circuit breaker to allow safe, 30 Amp at 120/250V AC max, connect and disconnect operation. This circuit breaker also gives protection against short circuits and provides added thermal time delay overload protection. The plug and receptacle contacts cannot be made or broken under load. When the plug is inserted, the plug and receptable contacts engage before the switch closes. When the plug is withdrawn, the switch opens before the plug and receptable contacts disengage. This provides the maximum safety of a dead front receptable. Arcing is isolated in a flame and dust-tight chamber. No special interlock device or manual switch, operators simply pull the plug straight out.
Suggested Applications: Manufacturing, Industrial, Warehouse, Lighting, Motor-Generator Sets, Compressors, Wet areas or Locations Where Combustible Dust is Present.
1. Deep recess contacts reduce accidental touching risks.
2. Spring loaded door seals receptacle when not in use.
3. Spring loaded brass receptacle contacts provide constant pressure and superior conductivity.
4. Mechanical cable clamps reduce cable strain and meet or exceed UL cable strain relief equirements.
5. Neoprene bushing compressed by cable insertion prevents water ingress into receptacle when in use.
6. 1-1/4" NPT tapped conduit openings on top and bottom of housing.
7. Interlocked circuit breaker provides safe connect/disconnect operation at 60Amp, 120/250V AC - Max.
8. Interlocked circuit breaker provides short circuit and thermal time delay overload protection.
9. Epoxy powder coat finish for durability.
