SCP and SCRP control panels use zero cross (burst firing) solid state relays (SSR's) in conjuction with external heat sinks to remove heat from the panel enclosure. These SSR's are manufactured with direct copper bonding technology and a built in varistor for surge protection. The zero switching relay switches ON when the sinusoidal curve crosses the zero and switches OFF when the current crossed zero. Zero cross SSR's create very low harmonics and RFI and are much more reliable.
Gaumer Solid State Relays include IP protected connections of cables with ring terminals. Testing can be made through the protective covers.
Solid State Relays are used with external heat sinks to remove heat from inside of the enclosure.

ZPA and ZPA3 series control panels use zero cross (burst firing) three phase analog SCR's (Thyristors). Designed for larger electric heater loads, these panels are available in sizes from 85 to over 2500 amps.
ZPD and ZPD3 series control panels use zero cross (burst firing) three phase digital SCR's (Thyristors). Designed for larger electric heater loads, these panels are available in sizes from 85 to over 2500 amps.
