16 A switching capacity and contact configuration
The 1SVR405600R3000: Rated 16 A at 250 V with a single changeover (1 c/o) contact — this is the current the relay can break under resistive or light inductive loads, not a momentary inrush figure. The 16 A rating sets the ceiling for pilot-duty control circuits or small motor contactor coils; if your load draws more than 16 A steady-state, step up to a 20 A or higher-rated relay. The control supply is 230 Vac, so the relay coil is designed for direct connection to a standard European or Asian line-voltage control bus without an intermediate transformer. That simplifies panel wiring — one less component to spec and mount.
Pluggable form factor — the relay base snaps into a DIN-rail socket (sold separately), and the relay module itself plugs in. That means a failed relay can be swapped in seconds without disturbing the wiring. The 1 c/o contact occupies one socket position, leaving adjacent slots for additional relays or timers in the same rail run.
