Siemens Industrial Controls 49AB01 Contact Kit
The Siemens 49AB01 Contact Kit is an essential NEMA auxiliary contact designed for field installation on Class 14, 17, 18, 22, 25, 26, 30, 32, 36, 37, 40, 43, 84, 87, and 88 motor starters and contactors. This Normally Closed (1NC) contact block provides reliable status feedback or interlocking within control circuits, rated for 10 Amp continuous current at 600 VAC. Engineered for NEMA Size 00 through Size 4 frames, the unit features a rugged snap-on side mounting design that allows for rapid integration without the need for specialized tools.
For industrial HVACR and motor control applications, the 49AB01 ensures precise switching logic in polyphase motor systems. The screw clamp terminals offer secure field wiring, maintaining high conductivity and vibration resistance in demanding environments. Technicians should verify the side mount clearance and dovetail alignment on the contactor crossarm during installation to ensure proper mechanical actuation and electrical continuity. This Siemens auxiliary interlock is a direct replacement for Innova and Furnas series accessories, meeting cULus and CSA standards for industrial control equipment.
Key Benefits- Universal Compatibility: Fits a broad range of Siemens NEMA starters from Size 00 to 4.
- High Electrical Rating: Heavy-duty 10A 600VAC rating handles standard pilot duty and control circuit loads.
- Simplified Installation: The snap-on side mount configuration reduces downtime during field upgrades or repairs.
- Reliable Logic: Provides a dedicated Normally Closed contact for safety interlocking or operational signaling.
Can this contact kit be used on Size 5 or larger contactors?
No, the 49AB01 is specifically engineered for the physical frame sizes and crossarm stroke of NEMA Size 00 through 4 starters.
Does this kit include more than one contact?
This specific model is a single-pole 1NC (Normally Closed) assembly. If a Normally Open or dual-pole configuration is required, a different part number (such as 49AB10) should be selected.
What is the maximum voltage for the pilot circuit?
The contacts are rated for 600V AC, making them suitable for standard industrial control voltages including 120V, 240V, and 480V circuits.
