EnglishWhat types of electrical measurement and control products does Hobut offer?
Updated
Hobut is a UK manufacturer of electrical measurement and control products, based in Walsall, and describes itself as the UK's largest specialist manufacturer in this field. Its range covers current transformers, panel meters, power meters, transducers and protection relays, alongside custom-designed solutions built to project specifications. The company states it employs over 150 staff and produces more than 50,000 current transformers and 20,000 panel meters per month, supplying customers worldwide.
Current transformers
Current transformers are the core of Hobut's product line, and the range includes several mounting and construction styles:
- Moulded case rectangular current transformers — five rectangular style moulded case units in compact cases, sized to suit a range of busbar dimensions.
- Split core current transformers — a clip-together, plug-in design that includes a short circuit link for safety during installation.
- Three-phase current transformers with built-in power meter — the C-Tran combines a three-phase multifunction AC power transducer with a three-phase current transformer in one unit.
Panel meters and power meters
Hobut manufactures panel meters as a major part of its output. One listed example is the M880 DMF DIN rail power meter, part of a DIN rail mounting power meter range. These sit alongside the company's broader panel meter production, which it says exceeds 20,000 units per month.
Current sensors and transducers
The CT132TRAN current sensor/current transducer range provides current sensing with a 0–5V or 0–10V DC self-powered output. This category covers products that convert a measured current into a standard analogue signal for use by other control or monitoring equipment.
Protection relays
- Earth leakage relays — variable earth leakage relays in compact 35mm DIN rail mounting cases, intended for use on three-phase electrical systems.
- Protection relays — listed as part of the overall product portfolio alongside transducers.
Custom-designed solutions
Beyond the standard range, Hobut designs and manufactures electrical measurement and control products to meet project customer specifications. This is relevant if a standard current transformer, meter or transducer does not match the busbar size, output signal or form factor your installation requires.
How to choose between product types
| Requirement | Product category to consider |
|---|---|
| Measuring current on a busbar with limited space | Moulded case rectangular current transformers |
| Fitting a CT around an existing cable without disconnecting | Split core (clip-together) current transformers |
| Combining current measurement and power metering in one device | Three-phase CT with built-in power meter (C-Tran) |
| Converting current into a 0–5V / 0–10V signal | Current sensors / transducers (e.g. CT132TRAN) |
| Detecting earth leakage on a three-phase system | Earth leakage relays |
| DIN rail mounted power monitoring | DIN rail power meters (e.g. M880 DMF) |
| A specification not covered by standard products | Custom-designed solutions |
