1. Product Name

Allen Bradley 140MT-C3E-B40 480V AC Miniature Contactor

2. Product Introduction

The Allen Bradley 140MT-C3E-B40 is a high-performance Allen Bradley Miniature Contactor, designed for 480V AC motor control in large-scale wheat agricultural and industrial systems, with robust build for heavy-duty operations.

3. Product Description

The Allen Bradley 140MT-C3E-B40 is a precision-engineered Allen Bradley Miniature Contactor, part of Allen Bradley’s 140M series optimized for medium-voltage motor management in high-demand applications. This Allen Bradley Miniature Contactor is specifically tailored to large-scale wheat agricultural operations—such as controlling industrial-grade grain silo conveyor motors, wheat processing plant mixer drives, and high-capacity irrigation pump systems—where 480V AC power is standard for heavy machinery and resistance to continuous operation, dust, and temperature variations is critical.

Constructed with flame-retardant thermoplastic housing (UL94 V-0 rating) and silver-nickel alloy main contacts, the Allen Bradley Miniature Contactor ensures stable performance in dusty grain processing facilities and high-load industrial environments. Its contacts minimize electrical arcing and wear during prolonged on cycles—essential for equipment like 24/7-operated wheat silo conveyors. The 140MT-C3E-B40 features a 480V AC coil (indicated by the “B40” designation) and a space-efficient design (approximately 72×45×28mm), enabling integration into crowded control panels of large wheat processing units or silo control rooms. It also includes built-in thermal overload protection to prevent motor damage from current spikes, a key requirement for heavy-duty agricultural machinery.

Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates reliably between -30°C and 80°C, handling up to 95% non-condensing humidity. It boasts a mechanical service life of 5 million operations and an electrical service life of 1 million operations, ensuring long-term durability across multiple wheat production cycles, while reducing maintenance downtime for large-scale farm and industrial operators.
