It carries 2 normally open instantaneous contacts rated for 10 A at 24 V AC and 230 V AC, with a 24 V AC 50/60 Hz coil.
The S00 footprint — 45 mm wide, 70 mm tall, 73 mm deep — fits alongside the matching S00 contactor in a compact panel layout.
The 2 NO contacts handle 10 A at 24 V AC and 230 V AC, 4.7 A at 60 V DC, and 3 A at 400 V AC. Arcing time runs 10 to 15 ms. These ratings cover typical pilot-duty and PLC-input isolation applications within a motor control center.
Buyers need to confirm compatibility with their control voltage; 24V AC is the specified voltage.
Ensures the part is not obsolete, avoiding supply chain risks for new designs or replacements.
Sourcing buyers need immediate procurement channels; highlighting distributors drives transactions.
Price transparency is critical for BOM cost estimation and budget approval.
Design engineers need to verify if the contact configuration (2 NO + 2 NC) meets their load requirements.
Buyers often look for equivalents from other brands for pricing or availability; answering this aids decision-making.
