FAQs
To install the AH1202L, mount the device in the panel cutout, connect conductors up to #14-10 AWG using the back and side wiring method, then tighten the terminals to 14 lbf-in torque. Ensure the actuator remains accessible for lock-and-key removal and verify the wiring path minimizes strain. This approach aligns with standard electrical codes and supports quick field upgrades without panel rework.
AH1202L is a maintained, lockable two-pole switch designed to accept a keyed actuator, enabling secure locking during service. Its locking feature prevents energization until the key is removed, satisfying LOTO requirements and reducing the risk of accidental startup during maintenance or inspections in industrial lines.
The switch is rated at 15A and operates at 120/277 VAC, suitable for control circuits in electrical panels. It accepts back and side wiring for #14-10 AWG conductors, with a torque rating of 14 lbf-in to ensure reliable terminations without damaging conductors during installation or maintenance.
AH1202L is cULus Listed NOM and NAFTA compliant, ensuring compliance with North American electrical safety standards and cross-border procurement requirements. These certifications support regulatory acceptance, supplier qualification, and safer integration into industrial automation projects.
By preventing unintended energization, simplifying wiring with back and side terminals, and offering durable, lockable operation, the AH1202L reduces unplanned downtime and maintenance overhead. Its robust construction and regulatory compliance translate to lower incident rates, faster repairs, and lower lifecycle costs for automated equipment.
