High Light 48V 600A Continuous Isolator ,800A Intermittent 2500A Starting ,ON-OFF Large Frame Disconnect
MT055 Large Frame Isolator — 48V, 600A Continuous, 800A Intermittent, 2500A Starting

At this current level the isolator stops being an accessory and becomes part of the power architecture. The MT055 carries 600 amps continuously, 800 amps intermittently, and 2500 amps during engine or motor starting, on systems up to 48 volts. It is intended for electric-drive craft, large lithium banks, thruster and windlass installations, and commercial vehicles where a small switch would simply be the weakest link.

Operation remains two positions, ON and OFF, with a hard stop at each. Simplicity matters here: a large switch that cannot be misread is safer than a selector with extra detents, particularly when the person isolating the system is not the person who installed it.

Everything about the installation is heavier too. Cable lugs are bigger, torque values are higher, and the surface it mounts to must carry real weight. The notes below focus on those details, because at 48 volts and several hundred amps, the termination is the part that fails first.

Rating Structure
Continuous 600A DC — sustained load while drive or charging systems run
Intermittent 800A DC — short bursts for thrusters, pumps or motor inrush
Starting 2500A DC — engine or motor start, seconds only
System voltage 48V DC
Positions ON-OFF, two-position rotary

Each figure has a purpose and none of them substitutes for another. Running an 800A intermittent load continuously will cook the contacts; treating 2500A as a working rating will do the same. Size the installation against the continuous number and use the other two as short-duration allowances.

48V Safety Reality
  • Arc energy — never operate the switch under load; shut the drive or engine down first.
  • Insulated tools — use rated tools and remove metal jewellery during installation.
  • Two-person rule — have a second person present when working on a live-capable 48V bank.
  • Lockout — leave the dial at OFF and note it in the service log before any work downstream.
  • PPE — face and hand protection when torqueing large studs on a high-current bank.
Build Details
  • Large-frame contact set — dimensioned for the continuous, intermittent and starting figures above.
  • Copper current path — minimises resistance and stud heating under sustained load.
  • Reinforced mounting base — resists distortion when heavy studs are torqued down.
  • Oversized terminal studs — accept large ring lugs without reducing cable cross-section.
  • Detented ON and OFF — the dial cannot creep out of position under vibration.
  • Clear face legend — state visible at arm's length and identifiable by touch.

Installation Requirements
  1. Isolate the bank, remove the negative lead first, and verify dead at both studs.
  2. Select cable cross-section against 600A continuous, not the starting figure.
  3. Mount on a flat rigid surface able to carry the weight of large cable without flexing.
  4. Bank positive to one stud, drive controller or distribution feed to the other.
  5. Use closed ring lugs only, crimped with the correct die, then torque both nuts fully.
  6. Cycle the dial once without load, reconnect, and check stud temperature after the first loaded run.
Inspection Schedule
Interval Check
After first week Re-torque both stud nuts; look for heat discolouration
Monthly in service Feel studs after a loaded run; clean any salt film off the housing
Season start Cycle ON-OFF, inspect lugs for corrosion, verify insulation on heavy cable
Any repair Replace cable with damaged lugs; never simply retighten a heat-affected joint

Buyer Questions
Is this suitable for a 48V electric drive?

Yes, that is a primary application, provided the controller is shut down before the switch is operated.

What cable size should I plan for?

Size for 600A continuous with margin, then confirm the lug fits the stud diameter.

Can it start a large diesel?

The starting figure is 2500A DC for a few seconds. Cable and terminations must be able to carry that burst.

Does it have a key or lockout provision?

This model uses a plain rotary dial. Key-operated and lockout variants can be quoted separately.

Are higher ratings available?

Larger frames and contact sets can be produced against your requirement or drawing, agreed before production.
