Control Transformer
Class 2
TCT50-05E07K
Description:
Triad control transformers come with tamper resistant shrouds for safety and a
steel bracket welded to the bottom of the transformer for ease of mounting. These
transformers are design and have the safety agency recognition for application
where a Class 2 transformer is necessary. Some of the applications would include,
but not limited to HVAC, Control boards, Lighting, etc.
