It covers an adjustable current response range of 11 to 16 A with a Class 10 trip characteristic, meaning it will trip within 10 seconds at 7.2× the set current — a standard for protecting standard induction motors during start-up without nuisance tripping on normal acceleration profiles.
This relay mounts directly onto a Siemens S2-size contactor via the contactor mounting fastening method — no separate DIN-rail footprint needed. The vertical mounting surface allows ±135° rotation and ±45° tilt front-to-back, which gives panel builders flexibility in tight enclosures. Side spacing to grounded parts requires 6 mm minimum clearance.
Electrical ratings and connections
Rated operational current is 16 A at 690 V, 50-60 Hz, with a rated insulation voltage of 690 V (pollution degree 3) and surge voltage resistance of 6 kV. Main circuit terminals are screw-type, top and bottom, accepting 2×(0.5-1.5 mm²) solid/stranded or 2×(0.75-2.5 mm²) finely stranded with ferrule. Torque spec is 3-5 N·m. Auxiliary and control circuits also use screw terminals, accepting 2×(20-16 AWG) or 2×(18-14 AWG). Short-circuit protection for the auxiliary switch requires a gL/gG 6 A fuse or quick 10 A fuse.
Power dissipation and thermal management
Per-pole dissipation is 3.5 W. This thermal load must be considered when grouping multiple relays in a confined panel — the 6 mm side spacing requirement helps manage heat buildup.
