Appleton XP hybrid circuit breaker panelboard
April 29, 2010 By Anthony Capkun
Appleton Electric has introduced a hybrid version of its XP explosionproof circuit breaker panelboard. By combining IEC technology and CEC/NEC standards in a single design, Appleton feels it has created a panelboard that is ideal for virtually any hazardous industrial location where flammable gasses or vapours are present—especially when used in the protection of lighting and heat tracing circuits. The hybrid XP incorporates a factory-sealed, cast explosionproof enclosure to house the arcing breakers, and a stainless steel terminal enclosure for field terminations. Factory sealing eliminates the need for field wiring and sealing fittings. Incoming/outgoing electrical connections are made in the stainless steel enclosure to secure DIN Rail mounting terminal blocks. Conduit or cable entries are created onsite by using a sheet steel hole punch. Available voltage configurations are 120/240, 120/208, 277/480 or 347/600. The XP hybrid is rated for the Class I, Division 2, Groups B, C, D; and Class I, Zone 1 and 2; and AEx de/Ex de IIB+ H2, T6. Other third-party approvals include NEMA/EEMAC: 3, 4, 4X, 7BCD, 9EFG, 12; and IP66.
