Heschen HSR1-25 Modular Contactor 25A 2Pole 2NC 24V AC Coil DIN Rail

Heschen HSR1-25 Modular Contactor 25A 2Pole 2NC 24V AC Coil DIN Rail

• 【2NC NORMALLY CLOSED LOGIC】 Configured with 2 Normally Closed (2NC) contacts—circuits remain connected by default and disconnect when the 24V AC coil is energized. Ideal for safety interlocks, emergency cut-offs, and HVAC fail-safe logic
• 【24V AC LOW-VOLTAGE COIL】 Engineered for 24V AC control systems. Accepts 24V AC signals from smart thermostats (Nest/Honeywell), HVAC controllers, and irrigation timers to safely manage heavy-duty 25A loads (AC-7a: 25A / AC-7b: 9A)
• 【TÜV & CE CERTIFIED SAFETY】 Rigorously tested and certified by TÜV Rheinland and CE for uncompromised electrical safety. Manufactured with high-grade flame-retardant housing to guarantee zero fire hazard during continuous operation
• 【ULTRA-LOW NOISE & DURABILITY】 Operates at a whisper-quiet noise level under 40dB, eliminating loud coil hums common in low-cost relays. Delivers an impressive 1,000,000-cycle mechanical endurance for long-term reliability
• 【EASY 35mm DIN RAIL MOUNT】 Standard TH35 DIN rail snap-on design for fast, tool-free installation. Compact 18mm module width saves valuable panel space in crowded enclosures. Screw terminals ensure secure connections
