GSE Timer Box III Contactor — IP44 Professional

GSE Timer Box III — IP44 Professional Contactor Timer

A serious professional-grade timer box — built around a Hager (Germany) timer and Iskra (Slovenia) contactors in a sealed IP44-rated housing with a cover and seal joint. One safety breaker switches the power circuits on and off. The right grade of kit for inductive loads like HPS lighting with their high switch-on current surges that cheap contactors can't handle reliably.

Why growers choose the GSE Timer Box III:

• IP44 protection rating — sealed against dust and water ingress, safe in humid grow rooms
• Hager timer (Germany) — premium European industrial-grade timer component
• Iskra contactors (Slovenia) — proper industrial contactors, handle high-current inductive loads
• Single safety breaker for ON/OFF — safer and simpler than multi-switch setups
• Designed for HPS and other inductive loads — handles the high switch-on current surge HPS lamps produce
• Cover and seal joint — protects internal components from grow-room environment
• Long service life — proper industrial components last far longer than hobby units

Who it's not for:

For simple single-light setups, a basic mechanical timer is sufficient and far cheaper. Premium pricing for premium build — for budget multi-light setups, MDF contactor boards are more cost-effective. Installation should be done by someone competent with mains wiring.
