The Honeywell MTL24571 Surge Protector is engineered to safeguard industrial automation systems from voltage spikes and transient surges. With a nominal input voltage of 24V DC and a maximum surge current capacity of 20kA, it effectively absorbs excess energy from power fluctuations. Featuring advanced metal-oxide varistor (MOV) technology, it responds rapidly (nanosecond-level reaction) to clamp voltages within safe thresholds. Certified by UL and IEC standards, it ensures compliance with global safety requirements. Ideal for industrial networks, control panels, and field devices in manufacturing, oil & gas, and chemical plants, it prevents equipment damage and downtime caused by electrical disturbances.
Built with durability in mind, the MTL24571 boasts a rugged IP20-rated enclosure that resists dust and minor impacts, suitable for challenging industrial settings. Operating seamlessly across -40°C to +85°C, it maintains stable performance in extreme temperatures. The compact 100 × 70 × 50 mm design supports DIN-rail mounting, simplifying installation in control panels. Its low power dissipation (<1W under normal conditions) ensures energy efficiency, while corrosion-resistant terminals guarantee reliable electrical connections over time. Whether used in indoor factories or outdoor installations, its robust construction withstands vibrations and harsh environmental stresses.
Designed for flexibility, the MTL24571 integrates effortlessly with various industrial automation setups, including PLC systems, sensors, and communication networks. Its modular structure allows parallel installation alongside existing equipment, enhancing system redundancy. The unit includes visual status indicators (LEDs) to monitor operational health, enabling quick diagnostics. Backed by Honeywell’s technical support and a 2-year warranty, it offers long-term reliability. Applications span smart infrastructure, machinery protection, and process control systems, where uninterrupted power supply is critical. Its combination of high-performance protection, ease of integration, and durable build makes it a trusted choice for industrial surge management.
