Product Description
Application
HHD11 series open-phase, phase sequence, Three-phase unbalance and Over/under voltage protection relay (hereinafter abbr. protection relay) is apply for AC 50Hz, 380V motor control circuitry which compose of AC contactor and other switching devices. When the motor's main circuit is on abnormal state, eg. out of phase, phase failure, voltage imbalance, etc. the protection relay will disconnect the switch contact and motor's three-phase power supply, so as to protection of the motor timely.
Main Technical Data
1, Working power: Three-phase 380V 50Hz, (85% to 110%) Ue fluctuations allowed.
2, Open-phase protection: Protection relay adopts sampling voltage (R, S, T front part ) and action when it detects any phase failure.
3, Phase sequence protection: When protection relay phase sequence is confirmed, if any phase line is exchanged, the motor will not start.
4, Voltage imbalance protection: for three-phase power supply, when any two-phase voltage imbalance comes to 50V ~ 75V, protection relay will act and protect the motor.
5, HHD10-C overvoltage protection: 445V ~ 465V not adjustable, delay 3s ~ 5s not adjustable; HHD10-D over-voltage protection: 400V ~ 460V (panel adjustable), delay 0.5s ~ 5s (panel adjustable) The
6, HHD10-C undervoltage protection: 290V ~ 310V is not adjustable, action delay time 3s ~ 5s not adjustable, HHD10-D over-voltage protection; 300V ~ 360V (adjustable at panel), action delay time 1s ~ 10s (adjustable at panel).
7, Open-phase protection action time 3s ~ 5s.
8, Phase sequence protection action time ≤ 0.2s.
9, Contact capacity: 3A AC250V (resistive).
10, Electrical life: 1×105 times.
11, Ambient temperature: -5 ºC ~ 40 ºC.
12, Alititude: ≤ 2000m.
13, Humidity: When the installation site's max. temperature is 40 ºC, the relative humidity ≤ 50%, it can allow a higher relative humidity at lower temperatures. eg. 20 ºC up to 90%. Special measures should be taken for occasional condensation due to temperature changes.
14, Installation: direct install, by DIN-rail.

FAQ
- What protections does the HHD11 series relay provide?
- It provides protection against open-phase, phase sequence errors, three-phase voltage imbalance, and over/under voltage conditions.
- What is the working power supply requirement?
- The relay requires a three-phase 380V 50Hz power supply, allowing for voltage fluctuations between 85% and 110% of the rated voltage.
- Is the over/under voltage protection adjustable?
- The HHD10-D model allows panel adjustment for both voltage thresholds (400V-460V over, 300V-360V under) and delay times. The HHD10-C model is fixed.
- How does the phase sequence protection work?
- If any phase line is exchanged, the relay confirms the incorrect sequence and prevents the motor from starting to avoid damage.
- What is the action time for phase sequence protection?
- The phase sequence protection acts very quickly, with an action time of less than or equal to 0.2 seconds.
- What are the installation requirements?
- The relay is designed for direct installation using a standard DIN-rail mounting method.
- What is the electrical life of the relay?
- The relay has an electrical life of 100,000 switching cycles.
- What is the contact capacity of the relay?
- The contact capacity is rated at 3A AC250V for resistive loads.
