Maximum load peak: 10xPn. 5 seg.

Maximum admissible voltage (in continuous): √(Pn x R*)

Maximum temperature on the hottest point on the resistor’s surface at nominal power: 375ºC

Operating voltage: 1000 v.a.c

Standard protection: IP00

Resistor tolerance: +-5%

Temperature 40% work cycle: –

Pn: Rated power / *R: Ohm value
