Feature → Business Impact → Application: The AHMC340C provides a 40A, 600V capability in a compact, open-panel design, enabling reliable motor control with minimal footprint. This directly improves control panel density and reduces wiring complexity, translating to faster commissioning and easier future upgrades in manufacturing lines. Application: Ideal for industrial machines and conveyors requiring quick toggling of three-phase motors with maintained contact under load. Feature → Business Impact → Application: Side-wired copper-alloy terminals support secure terminations for #14-8 AWG conductors, cutting termination time and minimizing field wiring errors. This leads to lower commissioning costs and more consistent electrical performance in panel assemblies. Feature → Business Impact → Application: Glass-filled nylon construction and a panel-mount format deliver durable operation in harsh factory environments, reducing part failures and service calls. Application: Suitable for general industrial control rooms and machinery panels where non-sealed enclosures are acceptable. Feature → Business Impact → Application: Certifications and compliance—cULus Listed, RoHS, NAFTA—provide documented safety, environmental responsibility, and cross-border procurement benefits, easing qualification for global projects. Feature → Business Impact → Application: Electrical characteristics—two-position, three-pole, single-throw toggle switch with maintained closure—offer straightforward operation and predictable behavior, supporting predictable maintenance windows and reduced downtime in high-volume production.

FAQs
For optimal installation, mount the AHMC340C on a standard panel, use side-wired screw and clamp terminations, and route conductors #14-8 AWG to minimize wiring congestion. The open enclosure design simplifies field wiring, and the unit is rated for up to 600 V and 40 A, making it suitable for most standard industrial motor starters in dry or controlled environments.
The AHMC340C is a three-pole, three-phase manual motor controller rated for 40 A and 600 V. It features a maintained contact, single-throw toggle switch with two positions, designed for panel mounting and side-wire termination. These specs ensure reliable control under typical industrial motor loads while keeping installation straightforward.
The AHMC340C carries cULus Listed, RoHS compliant, and NAFTA certifications, which support safety and cross-border procurement. However, it is listed as an open enclosure device and is not IP-rated for hazardous areas. For classified or harsher environments, consider enclosure upgrades or a variant with enhanced protection and certification suitability.
The AHMC340C features cULus Listed clearance, RoHS compliance, and NAFTA eligibility. These certifications matter because they validate electrical safety, restrict hazardous substances, and facilitate cross-border manufacturing and sourcing, reducing supplier audit overhead and ensuring conformity to regional requirements in industrial projects.
Maintenance benefits include a simple toggle switch with maintained contact and solid copper-alloy terminals that resist loosening under vibration, reducing downtime. ROI advantages come from quick installation, fewer components, and cross-border certs that streamline procurement for global facilities, helping achieve faster deployment and more predictable maintenance cycles in production lines.
