Functional Features:
- 4 NO main contacts for 3-phase + neutral switching
- Integrated auxiliary contact block (1NO+1NC)
- Snap-on DIN rail or screw mounting
- Coil status LED (optional accessory)
- UL/CSA listed for North America
Material Composition:
- Contacts: Silver-cadmium oxide (AgCdO) – weld-resistant
- Coil bobbin: Glass-filled polyamide (PA66-GF30)
- Arc chute: Ceramic fiber composite
- Terminals: Copper alloy, silver-plated
- Housing: Polycarbonate (PC) + PA66 – UL94 V-0
Structural Features:
- 105 mm width, 112 mm height, 113 mm depth
- Top-mounted auxiliary contact block
- Label window on front
- Coil terminals on top (for DIN rail) or side (for screw mount)
Working Principle:
DC coil energizes → magnetic field pulls armature → main contacts close → auxiliary contacts change state simultaneously. On de-energization, spring returns armature, contacts open. Arc chute extinguishes arc during opening.
Advantages:
- 100 A AC-3 rating in compact DIN-rail form factor
- Integrated auxiliaries reduce wiring
- DC coil eliminates AC hum and shading ring losses
Applicable Industries:
- Motor control centers (MCC)
- HVAC compressors
- Pump stations
- Industrial power distribution
Installation Requirements:
- DIN rail TS 35 or 4-bolt screw mounting (M5)
- Torque on main terminals: 3.5 N·m
- Torque on coil terminals: 0.6 N·m
- Minimum 25 mm clearance above for ventilation
Usage Notes:
- Must use DC coil – do not apply AC voltage (will burn coil)
- Always use snubber (RC) across coil for DC switching
- Derate current by 15% at temperatures above 50°C
