Overview

The SolaHD EMC-240B is a Type 2 AC surge suppressor engineered for 120/240 VAC distribution panels in industrial and commercial applications. Rated for 3 kA nominal discharge current and 80 kA peak surge current (8 x 20 µs), it provides robust protection against transient overvoltages with a clamping voltage of 395 VAC. The device supports all modes of protection (L-N, L-G, N-G, L-L) and features a 65 kA fault rating (SCCR) for safe operation. Designed for UL 1449 4th edition compliance, it includes status indicator lights, an audible alarm with silencer, and a test switch for monitoring. The EMC-240B supports remote monitoring via contacts (2 A, 125 V AC or 1 A, 30 V DC) and includes a 6-digit LCD re-settable surge event counter for tracking transient events. With a frequency range of 47–63 Hz and operating temperature from -40°F to 149°F (-40°C to 65°C), it is suitable for service entrance equipment and primary distribution systems. The device weighs 31 lbs (14.1 kg) and features thermally protected MOV technology with individual fusing. Installation is flexible, supporting top or bottom mounting on A-Series panelboards, and it is rated for altitudes up to 12,000 ft (3.66 km). A dedicated circuit breaker rated 60 A or above is recommended for local disconnect. Ideal for protecting sensitive equipment in factories, data centers, and commercial facilities, the EMC-240B ensures reliable surge protection to extend equipment lifespan and reduce downtime.
