ECPT81-1
The B & R Automation ECPT81-1 control module is a high-performance unit in the ECP Multi Control Modules series, designed for industrial automation and power distribution applications. It operates at a 24V AC voltage rating and supports a coil frequency of 50/60 Hz, ensuring compatibility with standard electrical supplies. This three-pole module delivers a current rating of 80A, providing robust capacity for three-phase loads, and incorporates silver alloy contacts for enhanced conductivity and arc wear resistance. The compact design integrates seamlessly into control panels, offering versatile mounting options without compromising performance or safety. With an IP20 degree of protection, this module is optimized for installation in enclosed panels, safeguarding internal components from solid objects larger than 12 mm.
Technical specifications for the ECPT81-1 are engineered to meet stringent industrial requirements. The module features 1 NO + 1 NC auxiliary contacts for flexible signaling and control circuit integration. It achieves a horsepower rating of 40 HP at 480V AC under AC-3 utilization category, specifically tailored for motor switching and inductive loads. The insulation voltage of 690V AC delivers a high safety margin against breakdown, while the mechanical life of 10 million operations and electrical life of 1 million operations ensure low maintenance and long service intervals. Its mounting type of DIN rail / panel mount allows for quick installation or retrofit in existing control architectures. With an operating temperature range from -5°C to +40°C, the module performs reliably across diverse industrial environments.
Operational features of the ECPT81-1 enhance system reliability and performance. The silver alloy contact material provides superior conductivity and extended arc resistance during frequent switching cycles. At rated conditions, the module sustains continuous operation up to 80A, while transient peaks are absorbed without degradation, thanks to robust contact metallurgy. The dual-frequency coil (50/60 Hz) design delivers consistent actuation characteristics regardless of line variations, reducing coil heating and improving lifecycle. Its IP20 degree of protection ensures protection against solid ingress when mounted in closed enclosures, while compliance with industrial ambient conditions preserves functionality under vibration and mechanical stress.
Integrated into broader automation systems, the ECPT81-1 simplifies control panel architecture and enhances modularity. Compatibility with standard DIN rail profiles and panel cutouts accelerates assembly in motor control centers and distribution boards. The auxiliary contact configuration allows direct feedback to PLCs or SCADA systems, facilitating real-time monitoring and predictive maintenance strategies. Ideal for use in manufacturing lines, HVAC systems, distribution panels, and process automation installations, the ECPT81-1 delivers a balance of flexibility, reliability, and durability required in modern industrial environments.
