Key Features Switch Type: ON‑OFF isolator / manual control switch — used to manually connect or disconnect circuits. Pole Configuration: 2‑pole design for switching both poles of a circuit. Contacts: Two normally open (NO) contacts — closes when switched ON. Compact Module: Slim profile suitable for modular panel mounting (approx. half‑module width). DIN‑Rail Ready: Designed for installation on standard DIN rails inside electrical panels. Clear ON/OFF position indication on the actuator for visual status of the switch. Electrical Ratings Rated Current: 16 A continuous load capacity suitable for general control and power circuits. Rated Operational Voltage: Designed for use up to 250 V / 400 V AC in typical low‑voltage systems. Rated Frequency: Usable on both 50 Hz and 60 Hz AC systems. Switching Category: Suitable for switching mixed resistive and inductive loads with moderate overloads. Short‑Circuit Breaking Capacity: Capable of interrupting fault currents up to 3 kA in typical installations. Rated Impulse Withstand Voltage: Provides robust dielectric performance to withstand voltage transients. Mechanical & Environmental Poles: 2 for switching of both line conductors. Protection Rating: IP20 at terminals when mounted inside an enclosure. Operating Temperature Range: Suitable for typical electrical panel ambient conditions. Mounting: Snap‑on DIN rail or panel mounting as part of modular control assemblies. Physical & Installation Module Width: Approx. 9 mm (half‑module) for space‑efficient panel installation. Dimensions: Compact form factor to fit standard control panel layouts. Terminals: Screw‑type or clamp connections for secure conductor installation. Weight: Lightweight design for easy handling and integration. Typical Applications Manual control of auxiliary circuits such as indicators, lights, fans, or pumps. ON‑OFF control input in control panels and distribution boards. Switching of electrical loads in industrial machines and automation systems. Panel‑mounted isolator switch for maintenance and safety applications.
