HLB3400T - 400Amp Trip Unit Description
HLB3400T - 400Amp Trip Unit
When you’re maintaining older electrical equipment, getting the specifications right matters. The HLB3400T is a 400-amp, 3-pole thermal-magnetic trip unit designed for use with compatible LB and HLB frames. It has a magnetic Hi-Low trip setting range of 2000–4000 and measures approximately 4.00 inches wide, 5.13 inches long, and 3.50 inches deep. That combination of frame type, amperage, pole count, dimensions, and trip range makes the HLB3400T a useful replacement component when an existing installation requires this configuration. Keep in mind that this is only the thermal-magnetic component, not a complete circuit breaker.
Key Features and Benefits
- 400 amp rating for compatible LB and HLB breaker applications.
- Three-pole configuration for installations requiring a 3-pole trip unit.
- Thermal magnetic design specifically intended for LB and HLB frames.
- 2000–4000 magnetic Hi-Low trip setting range.
- A practical choice for maintenance and replacement work where the HLB3400T is the specified component.
- Helps maintain the original form, fit, and function of compatible legacy electrical equipment.

Material Compliance and Certifications
Material compliance details and specific agency certifications were not provided in the available HLB3400T specifications. Rather than assume a listing or certification that may not apply, those details should be confirmed from the applicable equipment documentation when required for a particular installation.
Where It Works Best
The HLB3400T makes the most sense in existing electrical systems that use compatible LB or HLB frames and call for a 400-amp, 3-pole thermal-magnetic trip unit with a 2000–4000 magnetic Hi-Low trip-setting range. It is especially relevant for maintenance and replacement projects involving legacy electrical distribution equipment where matching the existing component is important.
