5 FAQs of DP-46 Three Phase Indoor Retardant Plastic Shell CT Low Voltage Current Transformer

What exactly is the DP-46?
The DP-46 measures alternating electrical current safely. It transforms high current flowing in power lines into a much lower, manageable current. This lower current safely connects to measurement devices like meters or protective relays. Its plastic case is fire retardant. It’s designed for indoor three-phase electrical systems.

Where should I install this current transformer?
Install it inside electrical panels or switchgear cabinets. It must stay indoors. The environment needs to be dry. Avoid places with lots of dust, corrosive gases, or strong vibrations. Mount it securely onto the current-carrying conductors you need to measure.

Why is the “retardant plastic shell” important?
The fire-retardant plastic shell is a key safety feature. It resists catching fire. It helps prevent flames spreading if severe electrical faults happen inside the panel. This protects nearby equipment and people. It’s much safer than metal cases which can get dangerously hot.

What electrical systems work with the DP-46?
The DP-46 works with standard low voltage three-phase AC power systems. Common system voltages are 400V, 415V, or 480V AC. Check its specific voltage rating. It measures the current on each phase conductor. It connects correctly to standard monitoring or protection devices.
