Durability (inductive load) = durability (resistive load) x reduction coefficient.

Resistive AC load

X Switching capacity (kVA)

Y Durability (Number of operating cycles)

A RXM2AB•••

B RXM3AB•••

C RXM4ΑΒ•••

D RXM4GΒ•••

Reduction coefficient for inductive AC load (depending on power factor cos ϕ)

Y Reduction coefficient (A)

Maximum switching capacity on resistive DC load

X Voltage DC

Y Current DC

B RXM3AB•••

C RXM4ΑΒ•••

D RXM4GΒ•••

Note : These are typical curves, actual durability depends on load, environment, duty cycle, etc.

For inductive load, to increase relay life cycles, please add a proper load protection circuit (eg: RC protection/Varistor/free Wheeling diode -DC load only- ).

For low level loads (below 10mA), we recommend to use RXM*GB series with bifurcated contacts relays instead.
