DADA Electric is a professional manufacturer and supplier of low-voltage circuit protection products. The CDADA DAM1 Series AC Moulded Case Circuit Breaker provides a flexible solution for customers sourcing a SACE Moulded Case Circuit Breaker for industrial and commercial power distribution systems. With rated currents from 10A to 1600A and an optional motorized operating mechanism (D), the DAM1 series supports different circuit protection and electrical operation requirements. Contact CDADA for manufacturer-direct product information, model selection and quotation.
The CDADA DAM1 Series AC Moulded Case Circuit Breaker is an advanced, high-performance low-voltage electrical protection apparatus engineered in strict compliance with international electrotechnical standards (IEC 60947-2, GB/T 14048.2). Built upon the proven SACE compact modular architecture, the DAM1 series covers rated operational currents from 10A up to 1600A across 6 distinct frame sizes (S1 125A, S2 160A, S3 250A, S4 400A/630A, S5 800A, and S6 1250A/1600A) for three-phase AC 50Hz/60Hz distribution systems with rated operational voltages up to AC 690V.
With a rated insulation voltage (Ui) up to 800V, the DAM1 series provides reliable overcurrent, short-circuit, and undervoltage protection for main power incoming cabinets, branch distribution lines, and motor feeders. Circuit breakers rated up to 400A can also serve as direct, infrequent starters and thermal-magnetic protectors for three-phase squirrel-cage induction motors. The series supports versatile mounting configurations—including vertical/horizontal panel mounting, front panel connection, rear stud connection, plug-in base, draw-out cradle, and standard 35mm DIN rail mounting for S1/S2 frames with dedicated clips.
Core Product Features & Selling Points
The DAM1 (SACE architecture) series is engineered to deliver distinct commercial and technical benefits:
● SACE Space-Saving Architecture: Compact dimensions (10%–20% smaller and lighter than standard domestic MCCBs) allow switchboard builders to design smaller enclosures, optimize busbar routing, and reduce international freight shipping costs.
● High Breaking Capacity up to 85kA: Available across 5 performance classes—B (25kA), N (36kA), S (50kA), H (65/70kA), and G (85kA)—delivering superior fault interruption capability for demanding industrial grids and main incoming panels.
● 35mm DIN Rail Mountability (S1 & S2 Frames): 125A and 160A frame sizes can be directly snapped onto standard 35mm DIN rails (EN 50022 / IEC 60715) using dedicated snap-on adaptor clips, eliminating panel drilling and cutting installation time by 50%.
● Flexible Thermal-Magnetic & Electronic Protection: Standard dual-action thermal-magnetic release with bimetallic inverse-time overload response, or the ST110-H intelligent electronic trip unit featuring MCU processing, 60%–100% current bar indicator, and ground fault protection.
● Modular Internal & External Accessories: Snap-in accessory compartments allow fast field installation of shunt releases (MX), undervoltage releases (MN), auxiliary contacts (OF), alarm switches (SD), rotary handles (Z), and motorized drives (D).

Global Export Experience & Customer Cooperation
When importing the DAM1 Series AC Moulded Case Circuit Breaker for overseas commercial and industrial switchgear projects, clients benefit from proven manufacturing consistency and dedicated engineering support across more than 40 countries:
" We selected CDADA DAM1 series SACE MCCBs (160A, 250A, and 400A frames) for our modular commercial distribution boards. The compact frame dimensions saved significant cabinet space, and the high breaking capacity of 70kA satisfied strict project safety requirements."
Frequently Asked Questions (FAQ)
Q1: How do I select the appropriate breaking capacity class (B, N, S, H, G)?
A1: Class B (25kA) and Class N (36kA) are designed for commercial sub-distribution and branch circuits. Class S (50kA) is recommended for standard industrial distribution boards and motor control centers. Class H (65/70kA) and Class G (85kA) are designed for main incoming switchboards situated close to high-capacity step-down transformers.
Q2: Which DAM1 frames support standard 35mm DIN rail mounting?
A2: S1 frame (DAM1-125) and S2 frame (DAM1-160) support direct 35mm DIN rail mounting (EN 50022 / IEC 60715) with dedicated snap-on adaptor clips, saving installation time in modular distribution boxes.
Q3: What are the differences between 4-pole Neutral configurations (3N, 4, 4B)?
A3: 3N: 3-pole breaker with an unswitched solid Neutral terminal bar; 4: 4-pole breaker where the Neutral pole switches synchronously without overcurrent protection; 4B: 4-pole breaker where the Neutral pole switches synchronously and is fully equipped with overcurrent protection.
Q4: Can the DAM1 Series be supplied as a SACE Moulded Case Circuit Breaker?
A4: The DAM1 Series can be equipped with an optional motorized mechanism (D) for electrical operation. Please confirm the required model and mechanism configuration when making an inquiry.
Q5: What is the difference between a motorized mechanism and a shunt release?
A5: The motorized mechanism (D) provides an electrical operating arrangement, while the shunt release (MX) is used for remote electrical tripping. They perform different functions and should be selected according to the application.
