Bistable relay 48VAC/24VDC 2NO 16A EPN526

Universal bistable relay – fast and reliable circuit control

Thanks to its latching mechanism, this relay changes the circuit state with a single button press – one press turns it on, the next turns it off. It operates with control voltages of 48 V AC and 24 V DC, enabling flexible integration with existing lighting and building automation installations. DIN rail mounting occupies minimal space (width = 17.5 modules, depth 63 mm), making it ideal for standard distribution boards.

Key practical advantages

• Dual NO contact configuration (2 × NO) – provides two independent contacts that close upon activation, simplifying wiring when controlling multiple lighting points.
• Switching current 16 A – sufficient for handling the heaviest domestic and industrial loads (e.g., small pump motors).
• Manual operation – allows manual state switching without requiring a control signal – useful for testing or emergency shutdown.
• Lighting compatibility: maximum switching capacity up to 1800 W for incandescent lamps and 800 VA (up to 1600 VA with DUO compensation) for fluorescent lamps – supports connection of both traditional lamps and modern LED sources.
• Low energy consumption – no-load current of only 6 mA, and power losses at full load amount to 2.4 W, minimizing operating costs.
• Environmental resilience: operating temperature range from ‑5 °C to 40 °C, and insulation class Ue = 250 V meets safety requirements for domestic and industrial installations.

Applications and compliance

This relay is suitable for lighting control systems (single-family homes, public buildings), building automation, and installations requiring simple switching of multiple points from a single signal source. The product complies with standard IP20 and holds RoHS and REACh certifications (SVHC-free), facilitating compliance with environmental and legal requirements when designing modern electrical installations.
