Grothe transformers 'MADE IN GERMANY' Bell transformers are optimized for short-term use, such as those found in bells, gongs, chimes and door openers in residential areas, while safety transformers are designed for continuous use. Grothe bell and safety transformers are protected by a PTC, which switches off the transformer on the primary side in the event of a short circuit or overload. If the PTC is triggered by an overload or short circuit, the transformer should be switched off briefly, but at least for 1 minute, so that it can then be put back into operation. All transformers meet the highest environmental protection requirements, are tested according to EN61558 and have been validated. Product features: Installation in electrical distributors/flat distributors Short-circuit proof thanks to PTC Meets the highest environmental protection requirements Tested according to EN61558-2-8:2011 Validated, marked with ENEC symbol Technical data: Primary: 230 - 240V AC (50 Hz) 90 x 36 x 55 mm (corresponds to 2 installation modules) Secondary: 4/8/12V AC (2.0/2.0/1.5A) Installation instructions: Note: Higher output voltage with low load or idle! after a short circuit, restart by briefly disconnecting the primary side from the mains for short-term loads (for continuous loads, we recommend the use of GROTHE safety transformers) Accessories for surface-mounted installation set: including two cover caps for IP 20 Accessories for surface-mounted installation set: including fastening rail and material for surface-mounted installation
