CP-T series moving iron panel instruments are predominantly used in the usual technical frequency range 15...100 Hz for alternating current and alternating voltage measurements in the ordinary technical frequency range 15...100 Hz. This instruments practically show independently of the wave form also at high harmonic content - the effective value of the alternating current. FEATURES M4 screw connections with clamps make this easier Clamping the connecting wires. Housing use matiral match UL94V-0 standard All fastenings suitable for shaking and shock resistance.
