Product details

Product Introduction

It provides Class 10 trip protection for three-phase AC/DC main circuits up to 690 V, with a rated operational current of 16 A.

The relay is rated for an operating temperature range of -20 to +55 °C and 0–90% relative humidity, covering most indoor industrial environments.

Mounting and Installation

Mounts directly to a Siemens S2 contactor — no separate base required. The mounting position allows ±135° rotation and ±45° tilt front/back from vertical. Side spacing to grounded parts must be at least 6 mm. Screw terminals for main circuit accept 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²) solid/stranded wire; torque to 3–4.5 N·m. Auxiliary contact terminals torque to 0.8–1.2 N·m.
