Final parameters, derating and ordering codes are always governed by the manufacturer’s latest datasheet for the exact version selected.

Selection starts with the operating conditions

The model family narrows the search. The exact ordering code follows only after the load, voltage, coil, environment, standards and volume are known.

01

Load

Resistive, inductive, motor, lamp, capacitor or DC fault duty

02

Electrical

Working voltage, continuous current, inrush and switching frequency

03

Control

Coil supply, tolerance, suppression and auxiliary feedback

04

Environment

Enclosure temperature, altitude, vibration, sealing and duty cycle
