1. Miniature 100-K / 104-K
• 5…12 A, 45 mm width for shallow commercial panels.
• 2-pole or 4-pole auxiliary blocks, spring-clamp or screw terminals.
2. Compact 100-C / 104-C
• 9…97 A, DIN-rail or base mounting.
• Electronic AC/DC coils (24…250 V) with built-in surge suppression; PLC-direct drive.
• 1 million electrical operations, IP20 enclosure.
3. High-current 100-E / 104-E
• 116…2 650 A, slim-line frame saves up to 30 % panel space.
• Universal electronic coil (24 V DC pickup power < 10 mA).
• Field-bus communication options, IE3-motor compatible.
4. Safety versions 100S-C / 100S-E
• Positively-guided or mirror contacts for ISO 13849 feedback loops.
• SUVA-certified, gold-plated twin contacts, AC/DC coils.
Common benefits
• One accessory platform: auxiliaries, mechanical interlocks, timers, surge suppressors.
• Global approvals: CE, cULus, CCC, EAC, RCM; RoHS compliant.
• UL witnessed short-circuit coordination when teamed with 140G/140MG breakers and 193 overload relays.
Typical applications
• Direct-on-line, reversing, star-delta, VFD bypass.
• HVAC pumps, compressors, conveyors.
• Safety door, e-stop, collaborative-robot circuits.
Selection tip
• Current ≤12 A → 100-K; 9–97 A → 100-C; ≥116 A → 100-E.
• Safety-critical feedback → 100S variants.
• Low-coil-power or PLC drive → choose electronic coil versions.
